HIP-AM W. STRONG AND CHARLES E. DAVIDSON, OF WICHITA, KANSAS, ASSIGNORS TO THE COLEMAN LAMP COMPANY, OF WICHITA, KANSAS, A CORPORATION OF KAN- sAs.

PORTABLE CAMP STOVE.

To all whom it may concern:

be it known that we, HmAM W. STRONG and CHARLES E. I.)AVIDS()N, citizens of the United States, and residents of Wichita, in the county of Sedgwick and State of Kansas, have invented a new and useful Portable lamp Stove, which invention is fully set forth in the following specification.

This invention relates to hydrocarbon stoves, but more particularly to a portable camp kit employing a hydrocarbon stove.

Objects of this invention are to provide anew and improved camp stove in which the fuel tank and associated feeding parts are positively connected to other parts of the structure without sacrificing features of adj ustability and compactness; to provide a connection between the fuel tank assembly and the remaining structure, having the unique features of construction, operation and arrangement hereinafter described; and

to provide a portable camp stove having the new and improved features hereinafter described.

Several species of which this invention is a genus are shown in the accompanying drawings, in which,-

Figure 1 is a perspective view of the portable camp stove showing the parts in position of use; Fig. 2 is a sectional view taken transversely of the casing; Fig. 3 is a view similar to Fig. 2 showin the parts arranged in preheating position; ig. 4 is a transverse section showing the parts in nested position; Fig. 5 is a transverse section of a modified form of connection in which the fuel tank assembly is detached from the link when packed in the casing; Fig. 6 is a fragmentary plan view of another modified form in which the link is pivoted to the upper part of the stove structure; Fig. 7 is a sectional view of the structure shown in Fig. 6 with the parts in operative heating position; and Fig. 8 is a view similar to Fig. 7 with the parts in preheating position.

The illustrated embodiment of the invention comprises a sheet metal casing 1 having bottom and side walls, and pivotally connected to one of the side walls may be a cover plate (not shown) so that the parts within the casing may be completely enclosed. Connected to the o posite end portions of the casing 1 are bale-like legs 2, which may be swung downwardly and locked in the position indicated in the drawings for supporting the casing, and for purposes of transportation these legs may be swung upwardly and snapped into position over the cover for preventing accidental dis placement of and injury to the parts. Pivotally connected to the inside of one of the side walls of the casing 1 is a wire grate 3, which may be supported in a horizontal position above the stove for cooking purposes.

Suitably mounted within and fixed to the casing 1 is a stove 4 which is constructed to use a hydrocarbon fuel for combustion. The stove 4, in this instance, is provided with a pair of burners 5, and in order that one of the burners may be used individually, an actuator 6 rests upon the bottom of the casing 1 and is connected to operate a valve for controlling the fluid passage leading to the lefthand burner, the free end of the actuator 6 projecting through an opening in a side wall of the casing, thus enabling the valve to be readily controlled.

For supplyin fuel to the stove 4, a fuel tank 7 is provi ed with 'a pressure pump 8 for creating pressure within the tank for forcing fuel from the tank through a feed tube 8, whichprojects at substantially rightangles from the tank 7, and from there through a vaporizer tube 9 extending approximately parallel to the tank 7. Connected to one end of the tube 9 is a bafiie plate 10, which is adapted to be arranged in close juxtaposition to a flat, vertical surface 15 of the stove a between the burners 5, and connected to the baffle plate 10 is a bracing strip 11, which is suitably fixed at its opposed end to the tank 7. A bracing strip 12 is connected to the tube 9 and tank 7 and is formed with an opening 13 through which the feed tube 8' extends, thereby providing a guard therefor.

For controlling the passage of fuel through the vaporizer tube 9, a valve is provided, having a squared projecting end 14,

which may be engaged by a socket key or other suitable tool for decreasing or increasing the fluid flow therethrough. From the above it will be apparent that the fuel supply tank 7, feed tube 13, and vaporizer tube 9 provide a unitary construction which may be bodily remove from the casing for replenishing the fuel supply or for other purposes.

-to be hooked over the lug When the parts are arranged in operative position for supplying hydrocarbon vapor to the burners 5, the end of the tube 9 is brought into alinement with the inlet opening 16 of the stove and the tube extends d1a metrically across a burner 5. In this position a notch 17 in the battle plate 10 will engage the U-shaped lug 18, which projects laterally from the stove.- Before the parts are arranged, however, in this position, it is necessary to preheat the end portion of the vaporizer tube, so that the gasoline or other liquid fuel flowing therethrough Wlll readily be vaporized. For this purpose a trough 19 is formed in the stove 4 at one side of and below the inlet opening 16, and an opening 20 in the stove structure 4 is arranged above and at one side of the opening 16 and communicates with the trough 19.

In starting, the end of the vaporizer tube 9 is brought into alinement with the inlet opening 20 so that the liquid fuel may pass into the trough 19, where it may be ignited by means of a match, and after the vaporizer tube 9 has been heated sufliciently the parts are shifted to the operative position above described. For holding the parts in preheating position, the lower end portion 21 of the baflie plate 10 engages the inside of the U-shaped lug 18, and for further insuring against accldental movement of the parts the bracing strip 12 is formed with a transverse groove 22 which is adapted to fit over an edge of the casing side wall, so that in order to move the parts from this position it is necessary to lift the tank 7 and thereafter move,the tank outwardly from the casing. A groove 22, spaced from the groove 22, assists in holding the assembly in operative heating position.

The above arrangement and general description are given by way of illustration and to enable the invention more clearly to be understood, but more particularly, in

accordance with the present invention, the

fuel feeding means may be positively cont nected to either the stove 4 or the casing A in such a manner that liability of the parts being accidentally displaced from operative position is prevented, thereby militating against explosion from escaping combustible vapors and insuring proper alignment of openings. As indicated in-Figs. 1 to 4, a substantially L-shaped lever 23 is pivoted at one end to a bracket 24 fixedly connected to the bottom of the casing 1, and formed on the opposite end of the link or lever 23 is an outwardly projecting hook-shaped lug 25. Formed in the inner end of the baflie plate 10 is an open1ng 26, which is adapted 25, and it will thus be seen that by grasping the fuel tank 7 the tank'may be moved to a os'ition wholly outside the casing 1, and w en not in use may be swung on the link 23 to a position wholly within the casing, as shown in Fig. 4, without at any time disconnectin the tank fromthe casing and without liability of tle parts becoming accidentally disp ace v In order to. guide the movement of the unitary tank and feeding means assembly when moved into and out of operative position, an upright guide plate 27 is fixed to ditions, however, it will be unnecessary to remove the supply tank and fuel feeding as sembly from the guide plate 27. The guide plate 27 also serves as a battle to prevent access of heat from the burners 5 to the valve 14 and associated parts, as well as to the feed tube 8 and this is particularly advantageous as it enables the stove to burn more steadily and without over-heating the parts.

In the modification shown in Fig. 5, an upright bracket 30 is fixed to the bottom of the casing 1 and pivoted thereto is'a link 23, the movement of which is limited by stops 31 on the brackets 30. An outwardly projecting lug 32 on the outer end of link 23 is adapted to extend through the opening 26 in the baffle plate 10. In this construction the baflie plate is connected to the link 23 and first moved to the position indicated by the dotted lines for placing the vaporizer tube 9 in preheating position, and thereafter the baffle plate is moved laterally into operative heatin position, and the movement in both directions is limited by the stops 31. When it is desired to pack the supply tank 7, the baflie plate 10 is detached from the lug 32 and thereafter the tank may be disposed within the casing and arranged similarly to the manner shown in Fig. 4.

Another modification is shown in Figs. I

6 to 8 in which the stove 4 is provided on the top with a cam surface 33, the portion thereof in the region of the preheater inlet opening 20 being inclined upwardly.

Pivotally connected to the inner portion of the cam surface 33 is a link 34 having a riding over the cam surface 33will elevate the baflie plate 10 suiiiciently for the vaporizer tube 9 to register with the preheater inlet opening 20, thereby to position the parts for preheating. Movement of the baffle plate 10 away from the trough 19 operates to lower the vaporizer tube 9 into registration with the inlet openin 16 in operative heatthe tank may be replenished with fuel, for

repair or for any other purpose. However, in a normal use of the stove, the fuel tank and vaporizing tube assembly does not have to be disconnected from the stove or casing structure, as the case may be, because when not in use the assembly may be swung into the inside of the stove, for example, as shown in Fig. 4, and when the parts are in position of use, the fuel tank is moved to a position entirely outside the casing. It will be seen that under normal operating conditions,

there is no necessity of detaching the assembly from the associated parts because, as

shown, in each instance a link mov'ably connects the assembly to the associated structure.

IVhile we have shown and described several specific embodiments of-our invention,

in accordance with the statute, it is to be understood that this is merely by way of illustration and numerous changes in details of construction, arrangement and o eration may be effected without departing rom the spirit of the invention, especially as defined in the appended claims.
